The staff was really nice about it, giving lots of announcements to keep everyone informed, answering all the questions of the commuters and organising things right away. I only had to wait for about half an hour, I expected a much longer delay. Congrats to the police and station staff for getting things organised so quickly. The guy didn't die (as I found out later). I heard someone say something that basically amounted to 'why couldn't he do it at a time when everyone aren't trying to get home'. That's pretty calloused.
Here's what Cityrail says:
From what information I can find on the internet, the same thing happened on Monday afternoon. Quoting someone who seemed to have witnessed both incidents, "Looks like he came back with a longer conducting rod". Oh, so that why the police wanted the power lines shut down.
From another person:
"An alchol induced individual was threatening to jump from about 3:15pm. The rozzers eventually dragged him away by 4pm. Power in the section was off for about 30 minutes while they tried to get him back over the railing. With the college of knowledge knocking off at 4, every man and his dog was trapped with nowhere to escape to.
Reports are it is the same individual from Monday."
Of the first incident on Monday, someone wrote "A problem was that some of the passengers were making things worse by giving the guy grief for delaying their trains home." Why would people say those things to someone trying to commit suicide? I don't know what made him attempt suicide twice at the same location, but I hope he'll be okay.
